This invention relates to a gas burner construction. The invention is directed particularly to a burner construction which provides a smooth, fiat and unobstructed top surface for receiving and supporting cooking utensils.

. In accordance with the invention, the burner embodies a body portion which provides ports for the issuance of gas for supporting the flame and a top portion positioned above the body. The top portion extends laterally to provide a surface for supporting cooking utensils and the lateral extent may vary. In some instances, the top portion may extend laterally so as to conceal the underlying body. A plurality of such burners may be employed with a suitable panel or plate so that the entire top of the rang is substantially closed and forms a substantially continuous fiat or plane surface. The top portion is preferably made so that it is easily removable for access to the underlying structure. The invention embodies the so-called double burner wherein there is an outer ilame for general cooking purposes and an inner or smaller flame for simmering purposes. In one form of the invention, the top portion may only cover and cooperate with the inner simmering flame. A further object of the invention is to provide an exposed surface member which is preferably formed of corrosion resisting metal such, for example, as Monel or any one of the variousstainless steels or other alloys which remain bright or resist corrosion.

The invention is disclosed by the structure illustrated in the drawings:

Fig. 1 is a top plan view of a portion of a stove or range showing fourof the burners oi. the present invention.

Fig. 2 is an enlarged cross sectional view taken substantially on line 2-2 of Fig. 1.

Fig. 4 is a view somewhat similar to Fig, 2 illustrating a still more modified form 'of the invention.

Fig. 5 is a plan view of the form shown in Fig. 4.

In Fig. 1 thetop panel of a range is illustrated at and this may be of suitable metal of sheet form and, insofar as the invention is concerned, it may be rolled steel'or a casting, although if it is a casting it is preferred that it be relatively thin as illustrated. This panel is provided with an opening 2 for each burner and preferablyv the burner top fits nicely in the opening although is a double type of burner.

2 Claims. ('01. 126-214) 5 as desired, and the number of the burners employed may likewise vary. A simple arrangement is shown in Fig. 1 which, it is believed, adequately demonstrates the thought.

The burner, illustrated in Fig. 2 and in Fig. 3, As illustrated, the burner has a body portion which may b a casting as shown at 5, provided with a hollow interiorv 6 which forms a channel, while a mixer tube, illustrated largely in dotted lines in Fig. 3 as at 15 l, connects into the channel and has its inlet end arranged to receive the gas jet 9 of a valve or the like. The mixer tube has an opening H! for primary air which is to be mixed with the gas issuing from the jet 9 and which is controlled This control for the primary air is subject to variation in so far as the present invention is concerned.

The burner has also a central part IS with a hollow interior It and connecting into the cham- The mixer tubes 1 and ll'may be similarly shaped and extend side by side so that the end of the tube H,

as at i8, is positioned adjacent the end of the mixer tube 1 and receives gas from an outlet jet I9. The mixer tube l has an opening 20 for primary air and a controlling valve 21 The disposition and location of the free ends of the mixer tubes may be varied and with the arrangement illustrated in Fig. 3, the several valves for gi fcontrolling the issuance of gas from their jets may be grouped as illustrated in Fig. 1 where the valves are generally shown at 25. Furthermore, each valve may be a double outlet valve which is well known to those versed in the art so that 40' each valve has two jets for the double burner.

'" any suitable means. The joint at 27 is, of course,

tight so that there is no issuance of gas but the part of the cap which seats upon the surface 2 8 is provided with grooves or channels 29. Thus,

a each channel 29 provides a port for the issuance of gas therefrom to support the gas flame.

The inner part It of the burner has a circumferential top surface 30 for receiving and supporting the top structure of the burner. This top structure includes a body part 3| arranged to substantially fit and rest upon the surface 30 and this part is provided with a grooved or channeled structure as illustrated so that when the same rests upon the surface 30, the channels form outlet ports 32 for the gas which supports the flame. The space 33 between the inner and outer portions provides for secondary air for the inner flame.

The body part 3| is provided with a screw threaded member 35 which may be threaded into the lower portion of the part I5 as illustrated. A laterally extending and load supporting disc-like part 4!! may be formed integrally with the body 3|. The portion 68 may be made of the material which may be considered unsatisfactory for providing the most desirable exposed surface and, accordingly, may be made of metal cheaper than that desired for the exposed surface. The top or exposed surface, generally represented at 3, is provided b a sheet of metal of disc; form, as shown at H, and this metal which may be of relatively thin stock may, and preferably is of corrosion resisting metal, such as Monel or any one of the several so-called stainless steels, or other alloys. The surface sheet 4! may be attached to the underlying support 48 in various ways, but as illustrated in Fig. 2, the sheet has wings or tabs 42 folded over and clamped against the underside of the support 48. As illustrated in Fig. 3, the supporting member d may be provided with notches at for receiving the wings so that the circular shape of the visible part of the burner is not interrupted. The. surface of the member at may, if desired, be in a plane which is the same as the plane of the panel l. However, it is preferred that the surface of the burner be slightly elevated relative to they panel I, as shown in Fig. 2, and the peripheral edge of the surface member is preferably bevelled as at 45. so that cooking utensils may be moved with sliding. action from the panel l onto the burner. When the burner is thus slightly elevated any overhanging part of a cooking utensil isout of contact with the panel Accordingly, it will be observed that. the underlying parts of the burner which actually supply the gas for supporting the flame, are. concealed from view and that a nice appearing top surface of the range is provided. When the burner is turned on the supporting member All and the surface member 4! are, of course, heated and; the heat transferred to the cooking utensil resting thereupon. This provides a measure of heat holdover in that when the burner is turned oifthe top part of the burner may remain hot for a considerable length of time. The burner is of an inexpensive construction in that the parts forming thegas chambers, such as the parts and i5 and the cap 26, are of usual construction. The part 3 I, however, instead of being" an ordinary cap is formed with the concealingoverlying disc construction. The assembly is easily made as it is only necessary to insert the screw threaded member 35 and revolve the disc structure until the body 3i moves home onto the seat 39. Likewise, it is very easy to remove the concealing disc structure if it is necessary to have access to any of the underlying parts; It might be pointed out that a suitable ignition system is to be employed for lighting the burners when the gas is turned on but this arrangement is well known to those versed in the art and will be located under the panel I.

In Figs. 4 and 5 a double burner is-illustrated with a top portion which cooperates primarily with an inner or simmering burner.

The body heated, by the inner or simmer flame.

of the burner may be the same as that shown in Fig. 2, and it has the same reference characters applied thereto. The top portion has a part 60 with a laterally extending supporting member El preferably provided with a corrosion resisting surface sheet 62. It will be observed that the top portion is relatively small and functions substantially only with respect to the inner or simmering burner. With this type of burner it is preferable to employ a grating structure 63 which overlies; the outer ormain burner ports so that the heat from the flame of the main burner may have direct access to a cooking vessel of larger diameter than the top portion 6!. This grating 63' may, if desired, extend only for a relatively short lateral distance and may be connected to andsupported by a, panel structure 64. In this form the top of the surface sheet 62 is preferably in substantially the same plane as the top of the grating 63 and panel 64. The purpose of this is so that a large cooking vessel, when placed over the burner, will rest directly upon the surface 82' and at the same time will be supported by the grating 83. It may be desirable to have the surface of the top 62 ele vated slightly with respect to the grating 63. When it is desired to use a small cooking vessel, or to simmer the contents of a large vessel, such a vessel may rest directly upon the relatively small top portion of the burner and be In this way the heat is transferred directly through the metal of the portions 6! and 62, to the, bottom of the vessel.
